Seachem Reef Iodide is a concentrated (8,000 mg/L) stabilized potassium iodide source for reef aquaria that will restore and maintain iodide levels to those found in natural sea water. It is formulated to provide a safe source of iodide that will not convert to toxic free iodine under storage or reef conditions. Iodine is as toxic as chlorine and should never be used in a reef system. However, iodide is as safe as chloride. Iodide is an important element required by invertebrates and many soft corals (gorgonians, sarcophytons, etc).

DIRECTIONS: Please note that each cap thread is approximately 1 mL, full cap is 5 mL.

ADVANCED: Add 1 mL for each 80 L (20 gallons*) daily to raise iodide by 0.10 mg/L. If necessary, adjust amount so that iodide reads 0.06 to 0.08 mg/L 6 to 12 hours after the last amount. Thereafter, use this amount daily and check iodide twice a month.

EXPERT: After determining the iodide consumption rate, set up a continuous drip system. Use the following formula to determine how much to add to your top-off water: m=0.5vi (m=mL of product to add to top off water, v=volume of tank in gallons*, i=amount to raise iodide in mg/L). For example, if you want to raise iodide by 0.10 mg/L in a 50 gallon* tank, then you would add 0.5x50x0.10=2.5 mL into the top-off water.

HINTS: It is normal for iodide levels to decline after a few days. This results from utilization and chemical depletion. Therefore, frequency of use will vary with different reef tanks. Dosing can be adjusted based on coral response.
